This data is
convenient
sampling. It
was collected at
random and
was easy to
create. The data
was collected
from ten 16
year old boys
and ten 16 year
old girls.

In the whisker box plot it
represents that the average
height of a 16 year old girl is at
least 15.2cm less than a 16 year

Height - Boys vs Girls
The height difference in the
results represented by the graph
shows that boys were almost
symmetrical in increase by
approximately 15 percent from
the shortest girl and boy
compared to the tallest boy and
girl. We were expecting that the
results would vary a bit more
because of the heights that were
collected; however the results did
prove to be very accurate.

The difference between the boys and
girls is on average, 1cm. In the
whisker box plot it shows that the
average weight of a 16 year old girl is
at least 13.4kg less than a 16 year old
boy.

The weight represented in the graph is represented in
much the same way as the heights; that is in a
symmetrical way, as it corresponded with the Body
Mass Index.
The dramatic rise in the boy’s data was likely to have
occurred because of the height of a few of the
participants, in relation to the overall average.

The Body Mass Index for boys and girls are
very similar using the average, as all of the
participants in each of the categories are
reasonably similar in height and weight.
This is clearly represented in the box and
whisker plot as well as the graph.
